Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The OP reflector is a specific type of reflector, it is commonly used in flashlights. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. The electronic switches may have a higher chance of standby drain.
